Hyun-Jin Ryu came off the disabled list to pitch four-hit ball over seven innings, and Matt Kemp singled in the go-ahead run to help the Los Angeles Dodgers beat the San Diego Padres 7-1 Sunday and avoid a three-game sweep. Ryu (14-6) struck out seven and walked none while allowing one run in his first start since a loss at Atlanta on Aug. 13, when he hurt his right hip. Ryu improved to 4-0 lifetime against the Padres. The seven runs were one more than the Dodgers scored in their previous three games combined.
